You probably heard about the Eclipse QSO Party that generated lots of activity during the Great American Eclipse of 2017. It also generated lots of science, currently being digested by the team at HamSCI. They presented preliminary results and talked methodology in this team-talk at the 2017 DCC, led by Nate Frissell W2NAF. (And they're all so young!).

Radio Rating: B-. There are lots of charts and graphs, and you'll miss some details, but the guys explain it pretty well, and the story is compelling.
